Cobalt is the brainchild of Oxeye Game Studio, which consists of Jens Bergensten, Daniel Brynolf, and Pontus Hammerberg.

Throughout its long development process it's become dense with features but the main thing to learn is that you play as a cute cyborg with a passion for 2d multiplayer battles involving extreme slow-mo and combat rolls.

Reviews:

"Cobalt is the 2D platform-shooter-brawler in which you can combat-roll into oncoming projectiles, trigger a glorious moment of auto-slo-mo, and knock whatever's headed your way back in the direction it came from." -Eurogamer
